Description
Technical field
The present invention relates to a kind of boundary mortar and preparation method thereof, relate in particular to a kind of special interface mortar for spray polyurethane rigid-foam skinning surfaces and preparation method thereof, generally be applicable in exterior wall exterior heat preservation system for spray coating polyurethane rigid foam or the spray coating polyurethane rigid foam waterproofing and thermal insulation of roofing system, can effectively solve the problem of spray coating polyurethane rigid foam outside surface crust layer mortar gellike material adhesive poor performance.
Background technology
A very important measure of building energy conservation is set up insulation energy-saving system to body of wall exactly, and the wall thermal insulating energy conserving system of China mainly contains exterior wall internal insulation system, the sandwich thermal insulated system of body of wall and external thermal insulation system at present.Wherein the external-wall external-insulation energy-saving system has become the main flow of wall thermal insulating form with its numerous advantage, and its major advantage is to protect agent structure, prolongs the buildings life-span, and the phenomenon of basically eliminate " heat bridge " helps ambient-temp-stable etc.In outer heat preservation system, the used material of thermal insulation layer mainly is styrofoam and extruded sheet at present, its thermal conductivity is lower, can satisfy existing energy-conservation 50% requirement, but,, even may arrive 75% or higher later on from energy-conservation 50% to 65% along with the further raising of energy-conservation requirement, like this styrofoam and extruded sheet difficulty reach energy-saving index, need to accelerate the exploitation of novel wall lagging material and heat-insulation system.Research and facts have proved that the hard polyurethane foam lagging material is the first-selection of present heat insulating material.
Hard polyurethane foam has a series of advantage, thereby it is had ready conditions as new lagging material.For example the thermal conductivity of hard polyurethane foam is low, good effect of heat insulation, and thermal conductivity is minimum in present all lagging materials, and its thermal property is superior; Have good adhesive property, urethane can be pasted with the external wall of a lot of materials, comprises various materials such as building block, masonry, concrete walls, timber, metal; Water resistance is good, because be the microcellular foam of compact structure, the surface that contacts with air is fine and close more, is difficult for permeablely, belongs to hydrophobic material; In-situ spraying or casting and constructing, good integrity; Ageing-resistant, fire-retardant, chemical stability is good, and site operation can realize stdn, industrialization, easy and simple to handle, its operating efficiency exceeds several times of other heat preservation construction modes.The hard polyurethane foam outer heat preservation system makes the building energy-saving effect remarkable because waterproof, insulation, heat-insulating technique are organically combined, and construction is simple.
At present, the constructional method of domestic polyurethane rigid foam exterior wall outer heat preservation system has four kinds: spraying method, casting, mounting method and dry-hanging method.Wherein unique urethane in-place foaming property and the self-adhesive ability of spraying method construction can make outer heat preservation construction convenient, improves operating efficiency greatly, and heat insulating layer good integrity; The spraying method construction is strong to basic unit's metope adaptability, promptly can be used for new building, also can be used for old housing reform and makes, and is applicable to the Any shape structure, particularly special-shaped aspect.
But after the moulding of in-situ spraying hard polyurethane foam, the surface can form the fine and close hard skinning of skim, and to improving urethane intensity, shock resistance reduces water-intake rate, keeps stable grade of thermal conductivity and all is of great benefit to.But then, such surface is disadvantageous as the substrate surface of next step operation to its bonding with outer alignment material.Therefore, interface processing is carried out on the hard polyurethane foam surface be absolutely necessary, otherwise alignment material directly is put on the hard polyurethane foam surface, be prone to layering rise rouse, come off, bad phenomenon such as cracking.
Because the spraying polyurethane heat-insulation system is shorter in the time that China uses, add the immature of market now, therefore the use at the interface treating agent of the spraying polyurethane skinning face of spraying polyurethane heat-insulation system is relatively more chaotic, can't effectively solve spray polyurethane rigid-foam skinning surfaces and be difficult for problems such as bonding and bonding be not firm, this stays hidden danger to spray coating polyurethane rigid foam heat-insulation system safety problem.
Summary of the invention
